where

\theta: Angle (°)
\Delta\lambda: Shift (pm)

Lecture brief

Historical brief

Beer attenuation, Compton (1923), Klein–Nishina, Bragg–Gray cavity and KERMA are the transport of photons and charged particles in matter. The sheets compute fluence, kerma and stopping. This sheet (RAD-28 — Compton shift) is the form associated with Compton. Working symbols: $\theta$ $\rightarrow$ $\Delta\lambda$ . λC = 2.426 pm.

Purpose

Purpose: compute

\Delta\lambda

from

\theta

in Radiation physics via

\Delta\lambda=\lambda_C(1-\cos\theta)

λC = 2.426 pm. Use it when a real radiation physics question must be answered in SI before a code check.

Live realistic example

In symbols

Live case. Given

\theta = 90.000\,\mathrm{^{\circ}}

, the governing relation

\Delta\lambda=\lambda_C(1-\cos\theta)

yields

\Delta\lambda = 2.426\,\mathrm{pm}

. λC = 2.426 pm. Move a slider: the numbers are this situation, not a canned story.
